Abstract
The utility model provides a rotary kiln supporting wheel device which prevents heat of a barrel body from being radiated to bearing pedestals, and has a heat insulation effect. The rotary kiln supporting wheel device comprises a base frame, wherein a supporting roller is fixed on each of two parallel supporting roller shafts; two ends of each supporting roller shaft are arranged on the base frame in a rotatable manner through the bearing pedestals; and heat insulation devices for preventing the heat of a rotary kiln from being radiated to the bearing pedestals are arranged on the bearing pedestals.
Description
Technical field
The utility model relates to rotary kiln, specifically, is a kind of riding wheel apparatus of rotary kiln.
Background technology
Existing rotary kiln comprises cylindrical shell, is distributed on the block more than two on the cylindrical shell periphery, and block is parallel to the axis of cylindrical shell, and the block integral solder is on cylindrical shell; The wheel band matches around cylindrical shell and with block; It also comprises riding wheel apparatus and catch wheel device.Riding wheel apparatus comprises underframe, each fixing carrying roller on two parallel roller carrier shafts, and the bearing block rotational fixation is passed through on underframe in the two ends of each roller carrier shaft; The periphery of wheel band is rotated and is supported on two carrying rollers.The wheel band forms rolling pair with two carrying rollers.It has above shortcoming: 1, since the block integral solder on cylindrical shell, owing to block can not with reasons such as cylindrical shell expands with heat and contract with cold synchronously, cause block to come off from cylindrical shell; 2, the two ends of roller carrier shaft are directly relative with cylindrical shell through bearing block, and the heat of cylindrical shell can radiation be given bearing block, causes the bearing block temperature to raise, and lubricating oil temperature raises, and makes bearing block fragile; 3, the spacing between two carrying rollers is difficult to regulate.
Summary of the invention
The purpose of the utility model provides and prevents that the cylindrical shell heat radiation from giving bearing block, having the supporting roller of rotary kiln device of effect of heat insulation.
The supporting roller of rotary kiln device of this effect of heat insulation; Comprise underframe; Each fixing carrying roller on two parallel roller carrier shafts, the two ends of each roller carrier shaft are rotated through bearing block and are arranged on the underframe, and bearing block is provided with the heat-proof device that the heat radiation that prevents rotary kiln is given bearing block.
The beneficial effect of the utility model: because bearing block is provided with the heat-proof device that the heat radiation that prevents rotary kiln is given bearing block, the cylindrical shell heat can radiation not given bearing block.
The riding wheel apparatus of above-mentioned rotary kiln, heat-proof device are an arc heat shield that is fixed on the bearing block shell, and the two ends of arc heat shield have opening.

The specific embodiment
Combine accompanying drawing that the utility model is done further to describe through embodiment below.
This rotary kiln as shown in Figure 1 respectively is provided with a circle block on three varying cross-sections of cylindrical shell 1.Each circle block respectively has 24, and is distributed on this cross section.Block is parallel to the axis of cylindrical shell.Adjacent two blocks and the end of cylinder body outer wall welding that are positioned on the same cross section of cylindrical shell stagger on the tubular axis direction each other; That is to say; The right-hand member of block 21 and cylinder body outer wall are through weld seam 71 welding, and left end is between two two limited blocks 31 that are fixed on the cylinder body outer wall.And on circumferential direction the block 22 adjacent with block 21, the left end of block 22 and cylinder body outer wall are through weld seam 72 welding, right-hand member is fixed between two limited blocks 32 on the cylinder body outer wall at two other.
The wheel be with 4 around cylindrical shell and with each the circle block match.Riding wheel apparatus 5 comprises each fixing carrying roller 53 on 51, two parallel roller carrier shafts 52 of underframe, and the two ends of each roller carrier shaft are rotated through bearing block 54 and are arranged on the underframe 51; Wheel rotates with 4 periphery and is supported on two carrying rollers 53.The structure that the bearing block 54 at roller carrier shaft two ends is slidingly arranged on the underframe is: on underframe 51, have perpendicular to the upwardly extending bolt slot in the side of roller carrier shaft, be used for the bolt 56 that bearing block is fixed on the underframe is passed bolt slot; Also be fixed with nut seat 57 on the underframe, be used for impeller-hub and be seated against perpendicular to the screw rod 58 that moves on the direction of roller carrier shaft and cooperate with nut seat, screw rod is parallel to bolt slot, and the end of screw rod contacts with bearing block.
Because an end of block and cylinder body outer wall welding, the other end does not weld with cylindrical shell, that is to say that the block other end can freely stretch at the cylindrical shell axial direction, and like this, cylindrical shell and block need not to expand with heat and contract with cold synchronously, so block can not come off from cylindrical shell.As for spacing in the cylindrical shell circumferential direction of the other end of block, guarantee through two limited blocks.Because bearing block is provided with the heat-proof device that the heat radiation that prevents rotary kiln is given bearing block, the cylindrical shell heat can radiation not given bearing block.In addition, the bearing block owing at least one roller carrier shaft two ends is slidably disposed on the underframe on the direction perpendicular to roller carrier shaft; Through moving shaft holder on perpendicular to the direction of roller carrier shaft, can change two spacings between the roller carrier shaft.
Claims (2)
1. the supporting roller of rotary kiln device that has effect of heat insulation; Comprise underframe; Each fixing carrying roller on two parallel roller carrier shafts, the two ends of each roller carrier shaft are rotated through bearing block and are arranged on the underframe, it is characterized in that: bearing block is provided with the heat-proof device that the heat radiation that prevents rotary kiln is given bearing block.
2. riding wheel apparatus as claimed in claim 1 is characterized in that: heat-proof device is an arc heat shield that is fixed on the bearing block shell, and the two ends of arc heat shield have opening.
